People say that processes take energy, which can be a bit misleading, because the total amount of energy never changes, just the entropy of it. Low-entropy energy is concentrated in a usable fashion, while high-entropy energy is spread out and hard to utilize. Our bodies take the concentrated energy of food, and we spread it out through heat, creating new molecules, moving, excretions, etc.</p></blockquote><p></p>
